Officers were called at 9:10 a.m. to Keeco LLC at 30736 Wiegman Road for a report of man who was bleeding, Krimm said.

When officers arrived they learned that a big rig with a trailer backed up into a loading dock and fatally struck Cheng, who worked at the business, Krimm said. Located east of Interstate 880 near Industrial Parkway, Keeco manufactures and distributes textile products for the home, according to its website.

The state Division of Occupational Safety and Health are en route to investigate the incident, police said.
